【発明の詳細な説明】 二 る ′Ｎ０ 本発明は容器に関する。[Detailed description of the invention] Two'N0 The present invention relates to containers.
本発明は殊にエアゾール容器のような、加圧物質のための容器に関する。The present invention relates to containers for pressurized substances, in particular aerosol containers.
二重壁を有するエアゾール容器は公知である。これらは当業者にとって公知のさ まざまな欠点を有する。Aerosol containers with double walls are known. These are known to those skilled in the art. It has various drawbacks.
例えば、容器を落とすなどして外壁が破裂しても、使用者を危険におとしいれな い二重壁容器を供給することが本発明の一目的である。For example, even if the outer wall ruptures due to dropping the container, it will not put the user in danger. It is an object of the present invention to provide a double-walled container with a high quality.
本発明によれば、弁によって閉じられる首を有する内側容器と首を有する外側容 器とを含み、内側および外側容器はプラスチック材から作られ、内側の首が外側 の首の中に配置されるように、外側容器が弁を除いて内側容器を包囲している、 加圧物質のための容器が供給される。According to the invention, an inner container with a neck closed by a valve and an outer container with a neck are provided. The inner and outer containers are made of plastic material, the inner neck is the outer neck the outer container surrounds the inner container except for the valve so as to be placed in the neck of the A container for pressurized substances is provided.
内側および外側容器は、首の上部を除いて結合されていないことが望ましく、該 上部は内側首の内面に係合するカラーと、外側首の外面に係合する弁のはめ輪と を用いて機械的に結合される。The inner and outer containers are preferably not joined except at the top of the neck, and the The upper part has a collar that engages the inner surface of the inner neck and a valve ring that engages the outer surface of the outer neck. mechanically connected using
外側容器が破壊した時、内側容器を安全に圧抜きし得るように、内側容器に少な くとも１個のオリフィスを孔明けすることができる。If the outer container ruptures, there is a small At least one orifice can be drilled.
望ましい実施例において、孔明けは、外側容器の最も弱い場所に配置される複数 のオリフィスによって形成される。In a preferred embodiment, the perforations are multiple holes located at the weakest point of the outer container. formed by an orifice.
本発明による容器の望ましい実施例を、軸線方向断面図で示す添付の説明図を参 照しつつ、実例のみにより、本発明の実施例を以下に説明する。Please refer to the accompanying illustration, which shows a preferred embodiment of the container according to the invention in axial section. By way of illustration only, embodiments of the invention are described below.
図示の容器は、一方の端に底部分１１が、他方の端に首（以後、内側首１３と称 する）につながる肩部分１２が設けられている本体を有する内側容器ｌを含む。The illustrated container has a bottom portion 11 at one end and a neck (hereinafter referred to as inner neck 13) at the other end. It comprises an inner container l having a body provided with a shoulder portion 12 leading to the main body.
使用時、内側容器１は加圧された物質、例えば化学生成物やロケット推進剤を含 む。In use, the inner container 1 contains pressurized substances, such as chemical products or rocket propellants. nothing.
容器はさらに、一方の端に底部分２１が、他方の端に外側フランジ２４が設けら れた首（以後、外側首２３と称する）につながる肩部分２２が設けられる本体を 有する外側容器２を含む。内側首１３と外側首２３の上面が実質的に同一平面内 に入るように、外側容器２が内側容器ｌを完全に包囲することが、図で明らかで ある。The container is further provided with a bottom portion 21 at one end and an outer flange 24 at the other end. The main body is provided with a shoulder portion 22 that connects to the outer neck (hereinafter referred to as the outer neck 23). It includes an outer container 2 having. The upper surfaces of the inner neck 13 and the outer neck 23 are substantially in the same plane. It is clear in the figure that the outer container 2 completely surrounds the inner container l so that the be.
エアゾール弁３は、外側フランジ３２、ガスケット３３およびはめ輪３４（アル ミニウムのスカート）が設けられた先細りの弁本体３１を含む、それ自体公知の いわゆる外側かしめ弁である。The aerosol valve 3 includes an outer flange 32, a gasket 33, and a ferrule 34 (aluminum a tapered valve body 31 provided with a minium skirt) known per se. This is a so-called outside caulking valve.
内側首１３の内方にカラー４が配置され、弁３の弁体３１がそれを貫通し、それ によって内側首１３がふたをされる。A collar 4 is arranged inside the inner neck 13, through which the valve body 31 of the valve 3 passes and which The inner neck 13 is covered.
首１３．２３の上面とカラー４の上面にガスケット３３が位置し、ガスケット３ ３はフランジ３２を支持し、したかりて弁体３１を支持する。A gasket 33 is located on the upper surface of the neck 13.23 and the upper surface of the collar 4. 3 supports the flange 32 and therefore the valve body 31.
内側容器１と外側容器２はその隣接表面全体にわたってきっちりしたはめ合いと なっているが、弁駁外は機械的に結合されていない。この機械的結合は、カラー ４と外側首２３のフランジ２４の下方にかしめたはめ輸３４とによって、首１３ ．２３にかけられる半径方向圧力により得られる。The inner container 1 and the outer container 2 have a tight fit over their entire adjacent surfaces. However, the Bengai is not mechanically connected. This mechanical connection 4 and a fitting 34 caulked below the flange 24 of the outer neck 23, the neck 13 ．． obtained by the radial pressure applied to 23.
先細りの弁体３１の細い内方端に浸漬チューブ５が取付けられる。弁３の残りの 部分自体は公知のものであり、説明を要しない。A dip tube 5 is attached to the narrow inner end of the tapered valve body 31. remaining of valve 3 The parts themselves are well known and do not require explanation.
内側容器ｌにはオリフィス１４が設けられる。！ないし１２個、またはそれ以上 の数を実際に使用することができるが、図には２個のオリフィス１４が示される 。オリフィスの断面が円形であるならば、その直径は、例えば０．１〜５ｍｍの 範囲である。オリフィス１４は外側容器２の最も弱い場所に配置されることが望 ましい。図示の実施例において、外側容器２は二つの部分、つまり、本体および 底部分２１を含む下部と、外側首２３の付く肩部分２２を含む上部とからなる。An orifice 14 is provided in the inner container l. ! or 12 or more Two orifices 14 are shown in the figure, although a number of orifices 14 can be used in practice. . If the cross-section of the orifice is circular, its diameter is, for example, between 0.1 and 5 mm. range. The orifice 14 is preferably located at the weakest point of the outer container 2. Delicious. In the illustrated embodiment, the outer container 2 has two parts: a body and a It consists of a lower part including a bottom part 21 and an upper part including a shoulder part 22 with an outer neck 23.
